1. Introduction
As the installation of Renewable Energy projects
continues to grow worldwide, so too does the need for
smart SCADA tools to manage their day-to-day
operations and optimize performance.
SCADA solutions are responsible for ensuring this is
performed to meet the needs of all key stakeholders.
SCADA solutions intended for Renewable Energy Control
Centers need to have a comprehensive approach,
adopting best-in-class digital tools to create a complete
suite, accompanying the data from real-time acquisition
to supporting O&M and strategic management
decisions.
Successful integration of state-of-the-art solutions into
one single product is key to solve the most complex
operational challenges.
One of the most important tools to be integrated in
SCADA solutions for renewable energies are digital
twins. These advanced analytical models are
increasingly used to solve problems arising from the
management of renewable assets such as wind farms
and photovoltaic plants to improve performance and
extend their useful life.
The key goal of digital twins and advanced analytics is
the use of data to gain important insights into the health
and performance of renewable assets to support the
decision-making processes for the operation and
maintenance of those assets throughout their useful life.
Understanding the performance, identifying
underperformance, and taking corrective maintenance
actions can deliver true value creation and extend the
lifetime of the assets.
There are two different approaches used to create digital
twins:
· Model-driven digital twin: this is built around a
deep technical analysis of a single unit of the
component and the fundamental physics behind it.
· Data-driven digital twin: based on data analytics
from an extensive population.
The following case study is focused on data-driven
digital twin based on real-time SCADA data using
INGETEAM’s INGESYS™ Smart SCADA product. Asset
owners can easily analyze this SCADA data using
Ingeteam’s analytics tool suite.
Note: Each renewable energy project has its own unique
characteristics linked to the environmental features and
topography of their specific location. No two projects are
identical, each asset owner faces different challenges,
depending on the mix of assets and systems it has. That
is why there is no one-fits-all solution and customization
is a key success factor when deploying such a system.

Deploying a data-driven digital twin
for the monitoring of a multi-technology
asset portfolio in Latin America
The use of data-driven digital twins and advanced
analytics to support the decision-making processes on
the operation and management of renewable energy
assets throughout their useful life provides multiple
benefits. INGETEAM’s INGESYS™ Smart SCADA
product, integrates these functions within its Renewable
Energy Control Center solutions.
An asset owner in Latin America, with a portfolio
spanning 4 countries, including wind farms and
photovoltaics plants, needed to unify the data generated
by its wind and solar assets to create value. The real
challenge was to build a central SCADA platform to so
that it could optimize its O&M strategy decision across
different technologies and countries.
All the data available was integrated into the INGESYS™
Smart SCADA to build the Digital Twin of its fleet,
through the creation of data-driven models for the
assets.
This was performed by:
· Detecting key component behavior changes and
trends. The operational performance of each plant
in the portfolio is monitored using Key Performance
Indicators (KPIs) providing an overview of the health
and performance of each unit. KPIs are
automatically created and can be easily used across
the asset owner organization to measure and direct
the O&M efforts.
· Integrating machine learning algorithms to detect
anomalies. Machine learning models for each key
component in the wind farms and solar plants are
created and deployed within the INGESYS™ Smart
SCADA analytics modules. These models learn the
normal behavior of the components and
continuously track performance, raising alerts to any
deviations from their normal patterns. These alerts
allow the technicians to focus their resources onto
the right units.
· Applying visual analytics. Time is a scarce resource
for field technicians. Visual analytic tools (see
examples below) allow technicians to easily explore
the huge amount of data generated by the assets
and identify performance issues without needing the
skills of data scientists.
· Analysis of performance and power curves. Asset
performance is a key factor that must be closely
watched. Machine learning models and KPIs detect
early deviations from the underlying trends.

Routine reports can be generated automatically, freeing up time for client technicians to focus on O&M tasks and
apply the insights gained through data analytics. This is achieved by means of easily customizable dashboards.
Below are three examples of issues identified thanks to the digital twin and data analysis:
· Identifying underperformance:
Using the digital twin created for the specific assets of the client, a comprehensive performance analysis was carried
out. This analysis detected that one of the wind farms in the portfolio was not performing as expected. Together with
the client, the root causes of this underperformance were analyzed and identified, and corrective actions
implemented at the affected wind farm. This is just one example of how the insights gained through data analytics
can be applied to correct specific problems. When the client detected a problem they were able to concentrate their
O&M efforts only on the affected wind turbines.
· Enhancing security:
Applied data science not only provides performance improvements. Security enhancements for aging assets is also
a key value driver in asset management. For instance, the client was able to spot abnormal thermal behavior in a
subset of the transformers. This insight allowed the client to launch an O&M campaign to correct the issue before it
escalated further.
· Curtailment losses:
In another example, the curtailment losses associated to a specific solar plant were calculated in fine detail and
economic savings were achieved by means of joints work with the transmission system operator (TSO).
Overall, the deployment of the Central SCADA improved the internal processes and decision making for managing all
the client’s assets. As a result, in the first year following the implementation of improvements, the client generated
estimated savings of over $500,000.

In Renewable Energy Plants
The use of digital twins and advanced analytics enables all users, from operators and O&M technicians, to
performance and reliability analysts and managers, to have the right tools and the necessary information to meet
their specific needs within one central platform. Information is available for each user type without division into
difficult to access silos. Within our Smart SCADA platform, a suite of specific tools can be optimized for each
specific stakeholder.
In the case study presented, we focused on the data-driven predictive tools inside our INGESYS™ Smart SCADA
platform. We have demonstrated how one customer with a portfolio of wind and solar assets in several Latin American
countries has achieved significant cost savings and improvements both in asset performance and security.
Moreover, the overall decision-making process was improved across the full organization, beginning with real-time
operators, field technicians and ending with skilled O&M analysts and managers.
As a result, we can conclude that INGESYS™ Smart SCADA was a key factor in the digital transformation of our
customer asset management.
As a result, in the first year
following the implementation of improvements,
the client generated estimated
savings of over $500,000.
